NY Daily News - Astronauts at International Space Station stage emergency spacewalk to fix apparent leak, May 11, 2013

Astronauts Chris Cassidy, foreground, and Tom Marshburn prepare for a spacewalk from the International Space Station on Friday. NASA discovered a leaking coolant line outside the station. The line chills power systems but power was rerouted and is operating normally. The six-member crew is not in danger.

"CAPE CANAVERAL, Fla. — Two astronauts took a hastily planned spacewalk Saturday to find and, possibly, fix a serious leak at the International Space Station. Flakes of frozen ammonia coolant were spotted Thursday drifting from the long frame that holds the solar panels on the left side. Less than 48 hours later, Thomas Marshburn and Christopher Cassidy emerged from the orbiting lab to hunt for the leak. They were prepared to replace a pump, if necessary."
